It is very easy to cause loading on a fixed-abrasive tool in the grinding process of soft metal materials such as aluminum substrates, and this leads to difficulty in the smooth running of the grinding process. Hence, a porous PVA (polyvinyl alcohol) stone is the only fixed-abrasive tool that is generally used until now. However, the PVA stone has some disadvantages that it is easy to be softered because of absorbing water during grinding, and high-density abrasive grains cannot be used due to precipitation in the polymerization process. In this research, a new high-porosity fixed- abrasive pad for grinding aluminum disks was developed. The method proposed to manufacture a high-porosity fixed-abrasive pad while Ti0_2 ultra-fine powders are added into the pad. This pad made of SiC or Al_2O_3 abrasive grains not only provided for a loading-free grinding process, but also had a better finishing roughness than PVA stones.
